我国县域单元功能空间分异的类型和差异性

hina has a vast territory, and the territorial space of each county is heavily different. As a result, the study of the study of classification and diversity of the territorial function in Chinese counties plays very significant role in mastering the spatial combination types of functional space in city and county level, the characteristics of the regional differences and the coupling mechanism of spatial pattern of major functional zone, and is very helpful for the development of the MFOZ planning program in line with China's national conditions, and reflects the different types of regional geographical characteristics. According to the result of the integrated spatial territorial evaluations of China, ecological space, primary producing space and development space is plotted, and the evaluation results are distributed into the county level, and the quantitative composition, relative proportion and spatial pattern of the functional spaces within the county are extracted to describe the functional space combination of the county unit. Then, according to the combination of the functional space of the county unit, the criteria of different spatial differentiation types are determined, and all the counties in the country are divided into several spatial differentiation types, and the spatial distribution reference values of the three basic regional functions in different types of counties are summarized. The combination of these three types of space and its different characteristics are summarized. Finally, based on the dominant strength of the major function, the first degree of the space and the composite situation of the major function and other functions, the comparison between the functional characteristics of the functional space and the function of the main body is analyzed, and the difference between the functional spatial differentiation and the major function several typical coupling relationships.
